Abstract

We investigate nanocrystals of ternary compounds Cd_XHg_1-XSe with 0 < X < 1 using a Raman scattering technique at room temperature. We obtained the correlation between nanocrystal (NC) chemical composition and the frequencies of CdSe-like LO and the HgSe-like TO and LO-modes. It is shown that the crystalline structure of the original CdSe NCs used for Cd/Hg substitution, either zinc blende or wurtzite, strongly affects the structural properties of the resultant Cd_XHg_1-XSe quantum dots and rods. © 2016 Society of Photo-Optical Instrumentation Engineers (SPIE).
